Steps
- Taking a dumbbell in your working hand, lean forward. Allow your working arm to hang perpendicular to the ground with the elbow pointing out. This will be your starting position.
- Flex the elbow to curl the weight, keeping the upper arm stationary. At the top of the repetition, flex the biceps and pause.
- Lower the dumbbell back to the starting position.
- Repeat the movement for the prescribed amount of repetitions.
Tracking it in OneRep
Add the standing concentration curl to a routine and your previous weight and reps sit beside every set, so the decision to add load is made by what is already on the screen rather than by memory. Exercise history and volume trends are one tap away, and logging works offline for the gyms where signal does not reach.
Because OneRep tracks food on the same timeline, a stall on this lift can be read against what you were actually eating that month — which is the difference between a programming problem and an eating one. More on that in tracking progressive overload without a spreadsheet.
Where the instructions come from
The steps above come from free-exercise-db, a public-domain exercise dataset. They are general guidance, not coaching for your body: if a movement hurts, stop and get someone qualified to look at it.
